Abstract

In April 2006 a heavy storm caused large quantities of ocean quahogs to be transported from their natural habitat, the soft bottom, where they live buried in the sediment, up onto a hard substratum at a lower depth. There, unable to burrow down again and escape, the clams were easy prey for predators. A year later, the diver revisited the site and observed empty shells and shell fragments, but no living clams.
